The integrated STEM activity described in this article incorporated two investigations that sought to develop children's understanding of fair-testing: (1) the first parachutes: how does the angle of a parachute frame affect the speed of descent?; and (2) modern parachutes: how does the size of the parachute canopy affect the speed of descent?…

Understanding ecosystems is challenging, but important for becoming environmentally-literate citizens of today's society. People have difficulty considering how different components, mechanisms, and phenomena, both visible and invisible, are interconnected within ecosystems. This research presents both the design and initial testing of an…

The paper traces a research process in the design and development of a science learning environment called WiMVT (web-based inquirer with modeling and visualization technology). The WiMVT system is designed to help secondary school students build a sophisticated understanding of scientific conceptions, and the science inquiry process, as well as…

A synthesis is developed to make biodiesel from vegetable oils such as soybean, sunflower, and corn oil, as an exercise in the laboratory. Viscosity measurements were used to gain an understanding of an intermolecular property of the biodiesel and that has limited the implementation of biodiesel on a wide scale basis, solidification at low…

Inquiry is an essential component of science. Furthermore, what students learn and how they engage in inquiry supported by technology is important to understand in order to promote science education reform. This paper presents an overview of work in curriculum and technology development and professional development. Collaboration with the Detroit…

Powerful Ideas in Physical Science (PIPS) is a preservice curriculum that provides modules for physical science courses designed for elementary education majors. Because the courses are built on the learning cycle approach, students develop concepts from activities and then apply this conceptual knowledge. A summative evaluation done by Horizon…
